C       James Randall of BPA suggested the linear scaling of angles during a
C       FREQUENCY SCAN  as explained in the July, 1997, newsletter.  First (this
C       subcase),  we show his old solution (note blank columns 57-64 of the
C       FREQUENCY SCAN  card).  This,  he says,  is wrong for engineering.  The
C       angles of the sources remain fixed at the values specified on the Type-
C       14 source cards.  At each frequency,  the source is balanced, 3-phase:
C       1st of 21 subcases (only 2nd is related to this first one).
C         21 March 2001,  expand to illustrate Pisa-format .PL4 file for normal,
C         old  FREQUENCY SCAN.  This is the 3rd of 3 Pisa-format illustrations.
C         The 4th subcase of  DCNEW-22  is for time simulation,  and the 15th
C         subcase of this same disk file is for verification of HFS.  While HFS
C         and FS should be structurally comparable,  in fact the illustrations
C         are quite different because this present example involves 2 output
C         parts (magnitude and angle) for each variable.  The 15th subcase only
C         involved a single output part.  This was the default,  and the most
C         common choice.  But polar output is not rare,  so had better be shown
C         to work for Pisa-format files.  To confirm that Pisa-format .PL4 file
C         really is being used,  turn on diagnostic printout for overlay 28 and
C         search the  .DBG  file for  LU4BEG.  Pisa will be mentioned.
$DEPOSIT, NEWPL4=2 { Use SPY DEPOSIT to change .PL4 file type from STARTUP value
C    To prove that Pisa-format code is being used,  it  is easy to turn on debug
C    printout.  Use here is like that pioneered in subcase 15,  which did HFS.
C    But diagnostic here requires more care because the network is bigger and
C    there are more harmonics (overlay 11 would produce a lot).  It is easiest
C    just to turn on diagnostic for plotting (see following card).  In the
C    .DBG file,  look for the name  LU4BEG  to see Pisa-related data values.

C     The preceding plot card was used until 21 March 2001 when this test case
C     was switched from normal C-like .PL4 file to Pisa-format C-like .PL4 file
C     by means of the assignment  NEWPL4 = 2  near the start.  It turns out this
C     changed the plot a little because the preceding plot request is to plot
C     all available points.  Whereas the nominal ending frequency F-max is 500,
C     ATP did produce a solution for 510 after completing 480.  This happens for
C     either type of .PL4 file.  But plotting is different.  The Pisa-format
C     file knows that the user-declared  F-max = 500,  and this will be read
C     from the disk file at the start of plotting,  thereby erasing the 510 that
C     was stored in memory.  The preceding plot card then would plot to 500, not
C     to 510.  To produce an identical plot,  we must specify  102 seconds (Hz)
C     per inch,  F-min = 0.0  and  F-max = 510  as follows:
 183102 0.0510.               SRC1A
C     Of course,  since these are nice round numbers,  the plot is so labeled.
C     Not so for the original,  which involved roundoff.  Remember, the plot
C     file is only single precision,  so 7 or 8 digits is the limit of math.
C     Look at the labeling after 1 inch:  102.000001     By switching to a Pisa-
C     format file,  such roundoff disappears.  The value is just 102.                                                                                                                  |

C       2nd of 21 subcases shows the "corrected" solution that James Randall  
C       says makes engineering sense:  the linear scaling of angles during
C       the  FREQUENCY SCAN.  Here the source is balanced 3-phase at the given
C       frequency (60 Hz),  but will be zero-sequence at the 3rd harmonic
C       (3 * 120 degrees = 360 degrees).  Since current is being injected,
C       the resulting voltage is a measure of the zero-sequence impedance.
C       A delta-connected transformer winding represents a high impedance
C       to such currents,  and this will produce high voltage at 180 Hz.

C         5th of 21 subcases illustrate  HARMONIC FREQUENCY SCAN  by Gabor Furst
C         using one of the new frequency-depend resistors.   The concept is more
C         general than just R in that it applies to R, L, and C  of series R-L-C
C         branch.  There are two points for each parameter,  allowing a straight
C         line to be drawn thru them for linear interpolation at each frequency.
C         Note values (R, F) = (5, 50) and (50, 500)  ===>  R(F) = F / 10.   The
C         inductance gives  X = wL = 6.28 * .01 * F = .0628 * F.  So, looding at
C         V-node of LOAD, impedance division ==> V = jX / ( R + jX ).  Dividing
C         out the jX,  1/V = 1 + 0.1 / j.0628 ) = 1 - j /.0628 ==> V = .28 +j.45
C         = .53 /__ 57.9 degrees.  So, V is a constant, independent of frequency 
C         because R is proportional to frequency.  This makes verification easy.

C   The CIGRE recommendation for frequency dependent load representation
C   is reactance Xp in parallel with an impedance Rs +jXs. With P active
C   and Q reactive, and h the harmonic order (where . ==> *,  V2 = V**2)
C   Rs = V2/P     Xs = A.h.Rs    Xp =  h.Rs / [(B.Q/P)-C]
C   To match preceding 2 branches,  Rs = 0.5 = 1**2 / P  ==>  P = 2.0
C   because source voltage is 1 volt rms.  Then  Xs = 2 = A * 1 * Rs
C   ===>  A = 4.  Finally,  Xp = 2 = 1 * 0.5 / [ B * Q / 2 - C ]  so to
C   keep this simple,  choose  Q = P = 2.  Then  B - C = 1/4  so choose

BEGIN NEW DATA CASE
C         18th of 21 subcases is added  21 November 2001  following corrections
C         to handle subharmonic data from Gabor Furst (see DC-22).  This is more
C         realistic data,  which was supplied as disk file  hfsnew1.dat    There
C         are  _several_  sources,  and several subharmonics.  In E-mail earlier
C         in the day, author Furst explained:  "The file I sent to you is an old 
C         file, the only modification done to it was the additions of the  sub-
C         harmonics. If you delete them the case runs correctly with the current
C         TPBIG.  I checked this."

C   3 February 2002,  true dynamic dimensions begin for F95 Lahey ATP.  Four
C   integers are read from a single, extra, isolated  $PARAMETER  card if that
C   card carries the request  <TABLE LIMITS:  to the left of column 33.  Then
C   4 integers are read using  FORMAT ( 32X, 4I8 )  and have meaning as follows:
C      LIMBLK  ---  limit on the number of  $PARAMETER  blocks;
C      LIMSYM  ---  limit on the number of  $PARAMETER  symbols (names);
C      LIMBLK  ---  Average number of references of each symbol;
C      LIMBLK  ---  Average length of symbols, in bytes.
C   F77 versions of ATP will process the card as F95 ATP would, but then will
C   ignore the 4 integers since tables are fixed.  Data thus remains universal.

C      is a little different and has meaning whether F95 or F77:

BEGIN NEW DATA CASE
C         19th of 21 subcases is added  25 November 2001  following corrections
C         to handle subharmonic data from Gabor Furst (see DC-22).  This subcase
C         began as separate disk file  PARATEST.DAT    Like the preceding subcase
C         this one involves HFS and subharmonics.  But it was fundamentally more
C         difficult because  POCKET CALCULATOR VARIES PARAMETERS (PCVP) also is
C         involved,  and harmonic number h is used within a  $PARAMETER  block
C         to define branches as a function of frequency.  Because of the use of
C         "h" within  $PARAMETER,  the initial harmonic number  HARNUM  must be
C         defined manually using the new  MINIMUM HARMONIC NUMBER  declaration.

BEGIN NEW DATA CASE
C         20th of 21 subcases is related to the 3rd.  Voltage sources are
C         converted to current sources in order to illustrate a generalization
C         that became effective  20 January 2002.  Luciano Tonelli of CESI in
C         Milano, Italy, had requested more than one current source at a given
C         node.  This was in E-mail of the EEUG list server two days earlier.
C         Prior to the change,  ATP should have halted on the 2nd source,  but
C         instead it continued with the scan to produce the wrong answer (it
C         would appear that only the final source at a node was being honored).
C         Well, the power-frequency source is split in two, each having half the
C         amplitude.  This should change nothing.  The same goes for the 200-Hz
C         contribution.  The answer should be unaffect by this splitting.

C         by the 3rd subcase of DC-36.  Answers of the present subcase are same
C         as  DC8.LIS  because of the degenerate nature of the dependency that
C         is being used.   Other than the name of the disk file in the  $INCLUDE
